Abstract: PURPOSE:To prevent improper oil from being supplied to a storage tank by providing a device for distinguishing the kinds of oils to the oil filling pipe for a storage tank and controlling the opening and closing of the valve provided on the oil filling pipe by means of the output of said oil-kind distinguishing device. CONSTITUTION:An oil filling pipe 14 connected to the storage tank of a filling station is coupled to a hose 21 on the tank-lorry side through a coupling 20. A three-way selector valve 18 is provided to the oil filling pipe 14 and a bypass pipe 22 is connected between one outlet of the selector valve 18 and the oil filling pipe 14. In the bypass pipe 22 is formed a housing 23, in which a float 24 is vertically movable housed, while a float switch SW2 actuated by the float 24 is also provided. When the oil being filled is the right one, the float 24 is not floated up to the dotted-line position 24a, thereby without causing the switch SW2 to be turned on. If the oil is a wrong one, the float 24 is floated up causing the switch SW2 to be turned on. This causes the three-way selector valve 18 to close, stopping the filling of this oil.

Filed: 1982-11-30
Abstract: PURPOSE:To perform accurate control to return a lens by a little distance under the pose mode, by installing an adder which inputs a return pulse and forward pulse of opposite polarities and a coupling condenser which supplies the output signal of the adder to a lens driving circuit. CONSTITUTION:When a lens return controlling signal D is generated, the output signal G of an inverter 18 also becomes ''L'' and is outputted from an adder 16 as its output signal I. The output signal I of the adder 16 is outputted to the output signal of a coupling condenser 23 under almost the same conditions and the output signal K of the condenser 23 is supplied to another adder 6 through a variable resistance 24 for level adjustment. The adder 6 adds the output signal K of negative polarity to the output signal C of a loop filter 2 and outputs the added result. However, since the output signal C is composed only of a DC component because a lens servo loop is interrupted in the period when the output signal K is generated by means of a switching circuit 12, a lens driving circuit 4 executes lens returning control of about 10 seconds in accordance with the time width of the lens return controlling signal D.
